SPECIFICATION forming part of Letters Patent No. 505,920, dated October3, 1893.

Application filed March 10, 1893- To all whom it may concern:

Be it known that I, HARRISON S. MARTIN, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Cork-Extractors, of which thefollowing is a specification, reference being had therein to theaccompanying drawings. 7

Figure 1 is an elevation from the rear of a device embodying myimprovements. Fig. 2 is a view showing the interior parts of the casingbeing divided, and some of the contents being shown -in section. Fig. 3is a similar view of the other part of the casing. Fig. 4 is a sectionof the casing taken at right angles to Figs. 2and 3. Fig. 5 is afrontview. Fig. 6 is a section on the line :20, 00, of Fig. 5 and on a largerscale. Fig. 7 is a sectionon the line y, y, ofFig. 5. Fig. 8 is a sideView of the bottom part of the device. Fig. 9 is a perspective of thenut and its plate. Fig. 9 shows detached, the cam plate for moving thenut and holding it in its operative position. Figs. 10 and 11 show amodified form of extractor.

Acasing or tube is constructed in such "way as to properly support thecorkscrew and the parts which operate it and also the parts which holdand support the bottle, this casing being made in two halves or parts A,A, so asto reduce the cost of the implement by avoiding the necessity ofcoring in casting. The two halves of the tube or casing are firmlyjoined together by suitable devices such'as a screw cap a. at the topand ears a, a, which are fastened together by screws, as at a The casingparts are so shaped as to provide a slot B in the rear, and a slot 0'epposite thereto in the front side, and also slots D in the sides, andthese serve purposes to be described below.

A indicates the base piece or pedestal by means of which the implementcan be firmly fastened to the table, or other support, and which may becast integral with one of the casing parts A, A, or cast partly with onehalf, and partly with the other. The walls of the interior chamber areflared somewhat at the bottom, as shown at b.

E indicates the cork screw, it being secured to, or formed with thescrew stem or shank which rotates it. Preferably it is inserted SerialNo. 465.438, (No model.)

into the lower end of the screw F. This screw F is mounted in avertically sliding frame or carrier G, which is formed with the rearupright bar g, the bottom cross plate g, the top plate 9 and the camplate 9 these parts beingpreferably allcast integral. The rear Verticalbar 9 has rack teeth g and with these a toothed wheel orsegment Hengages, the shaft of which wheel is mounted in a bracket I whichextends back from the tube or casing.

J indicates a handle which is secured to the wheel or segment H, and bywhich the latter can be rocked in such way as to throw the frame orcarrier G up and down in the casing. The carrier G is formed withbearings in' the top and bottom plate and g for the mounting of thescrew so that the latter is free to rotate relatively to the carrier,and can at the same time be moved bodily up and down with it.

The interior of the rack frame is hollow, or open, and is thereforeadapted to permit an advantageous arrangement of the nut which is placedwithin the said chamber, as will be explained, that is to say the nutcan be placed between the ends of the rack frame, vertically. Asthecarrier Gand the screw F move L is a nut of the-nature of a pin or shortarm projecting outward from one of the casing walls. This nut pin iscarried by a plate L, having the guide-part Z anda shoulder at Z. Thepart Z is fitted in a guide-way formed by ribs 41, 01., upon one side ofthe chamber within the casing. The part Z is shorter than the guide-wayso that the plate and nut pin can slide to some extent. The shoulder atZ is so situated that the plate can be engaged by the cam part g of thevertically sliding frame G, and when such engagement occurs, the nut pinL will be held rigidly in position at the point where it engages withthe screw F.

The actions of the parts described will be readily-understood. As thecarrier G descends the screw F will be rotated because of its engagementwith the nut pin L, and such rotating of the screw causes the corkscrewE'toperforate and enter the cork in the bottle. But when the movement ofthe carrier G is reversed and it is thrust upward the pressure of thethread on screwF will compel the nut pin L to move laterally out ofengagement with said thread, the part Z of the nut plate being shorterthan the guide-way at 'lt n to permit this escaping motion of the nut;and

5 therefore during the first part of the upward motion of the carrier Gneither the screw F nor the corkscrew E will be rotated, and hence thecork will be drawn from the bottle. But as soon as the cam plate q comesin contact with the shoulder Z of the nut plate, the

latter will be moved back along the guideway formed by the inclinedguides at n, and held in such position that it is compelled to engagewith the thread of screw Rand the latter commences to rotate andcontinues to so rotate during the latter partof theupward travel of thecarrier G. This'rotation is in adirection opposite to that of therotation during the descent and therefore thecork screw, E will be drawnout from the cork.

Forthepurpose of holdingth'e bottle firmly during the operationlofdrawing the cork,I,1 employ laterally movable jaws N, N,so situ-l atedthat theycan be adapted to surround} more or less of the neck of thebottle. They: are moved by bars 0,0 with which engage lugs P that arecarried by the plungeror can '1 rier G. As shown there is an armp'qwhich projectsthrough the slot Of, and'has across piecep forsupporting these lugs. The bars 0 O are preferably more or less elasticso i that they can act to open the jaws N, and}; also can applyayielding pressureytolthe jaws as the lugs P movedown. i j, M is a stopplate which can rise and fall; within certain limits in the bottompartofthe chamber in the casing, it having projections D which jfit inthe slots D. This plate moves up with the cork as the latter rises, 40but stops it at the proper point to have the screw withdrawn.

' Asomewhat modified form of the extractor is shown in Figs. 10 andll.Here the nut L isattached to a sliding carrier L, which has ribsorprojections that fit in groovesor slots D in the sideof the casing. Italsoycarrieseye-pieces P or lugs, whichengage withj the jaw-supports orcarriersO O. The jaws,

N are not pivoted asin Figs. 1 to 4, but'can 5o move out andininasmuchas the spring parts support them entirely. The upper portions 0 of thejawcarriers are elastic, audat 0 there are cam-like shoulders, andwh enthe 1- nut carrier L moves down, the eyes P en 5 5 gage with theseshoulders and force the jaws N inward,so,as to grasp the bottle neck,and theyare held in until the nut carrier has reached again the upper.end of its play. The nut carrier in this case is somewhat dif- 6oferent from the plate used in theother construction,it hereconsistinglof avertical bar, with a nut projection at L which compelsthe screw F to rotate at the times that the carrier L is stationary,attheupper and the lower 6 ends ofthe slots D.

I have found that a nut projection of the character of that shown at Lor L is much superior to those which entirely encircle the screw, as thelatter have enlarged wearing and bearing surfaces .which increase thefriction, and, moreover, unless the parts are fitted very accurately byexpensive labor, they frequently tend to bind or cramp in the casing,and in turn, bind upon the screw. A nut like that at L cannot cramp orbind, or become clogged with grit or dirt, or be seriously worn, as itand the thread or groove in the screw are practically self clearing. Byhaving thenut situated inside of a rack frame or carrier like that at Grwhich is hollow or formed with an interior nut chamber, and is movableindependently of said carrier, I am able to shorten p the mechanism as awhole, and make it more compact than are those which are so arranged asto requirethat one -or more nutsbesituated aboveor belowthe rack frame.

Thespring carriers OCQrO fOr the jaws N v or N provide am uch simplermeans for-open- 'ing and closing the llatterthan those usedxintheearlier constructions, as the parts 0, can, of themselves, performjbothlof the above described functions, namely ;imparting inwardmovement to the jaws, and holding thei-latter under a yielding pressure;,lEleretoforetemployment has been made uof a complicated mechanismforaccomplishing this purpose it comprising two or more hinged levers,and sliding wedges supplemental to the spring parts. In the present.construction two spring bars and aJug arelall that are necessary.

What I claim isr 1. In}a cork extractor,-the combinationwith thetubular-casing, the-rackframmthetoothed wheel for positively lifting anddepressing the;frame,the screw mountedrtherein,-the;nut adapted to slidefrom one horizontal line to another, and means carried by the rack framefor'moving the nut toits operativelpositions, of the Verticallyarrangedelastic spring carriers secured rigidly to the casing and extendingdownward by the side 1th ereof,the aws N connected to the said spring1carriers, and lugs 0 bearing directly against theouter sides of thespring carriers and adapted to bend them, substantially as setforth.
